I have some ceramic coatings. I coated the turbochargers on my diesel and the cast iron turbo manifold.
This engine has 150,000 miles. Problem is it has 4.10 gears and the top gear in the 3 speed transmission is 1:1 so the engine screams anything faster than 70mph. Which wears them out faster.
This engine will get a 4 speed over drive transmission with lockup converter and 3:1 or 3.25:1 rearend gears behind it eventually.
That will bring the final drive line ratio from about 4.5:1 with non lockup converter and 4.10 gears to about 2.1:1 with an over drive transmission, lockup converter and 3:1 rear gears.
With an engine that can make upwards of 500hp and 600 torque there is no reason to run final drive gear ratios anywhere near 4:1.
